Seawater contains sulfate concentrations that are nearly 40 times those measured in plasma. Therefore, it is easy to see why fish would need to develop mechanisms to keep sulfate within a physiologically normal range. The kidneys of teleost¬†fish have been known to¬†excrete excess sulfate in the urine. However until now, it was not known whether…

I came across this neat video from Mayo Clinic researcher Dr. Michael Romero, a comparative physiologist interested in how the kidneys work. In this video he describes discoveries made in zebrafish that relate to human kidney function:

Researchers at Massachusetts General Hospital (Boston) have successfully regenerated kidneys that were unsuitable for transplantation. They stripped the tissue of all native cells, then added donor stem cells to the scaffolding that was left behind. The re-animated kidneys successfully created urine after being transplanted into rats! The hope is to apply this technique to humans…
